CQ-DF583U
❐What is MP3/WMA?Common
≥High bit rate and high sampling frequency are
recommended for high quality sounds.
≥Selecting VBR (Variable Bit Rate) is not recom-
mended because playing time is not displayed
properly and sound may be skipped.
≥The playback sound quality differs depending on
the encoding circumstances. For details, refer to
the user manual of your own encoding software
and writing software.MP3
≥It is recommended to set the bit rate to “128 kbps
or more” and “fixed”.
WMA
≥It is recommended to set the bit rate to “64 kbps
or more” and “fixed”.
≥Do not set the copy protect attribute on the WMA
file to enable this unit to playback.
Caution:
≥Never assign the “.mp3”, or “.wma” file name extension to a file that is not in the MP3/WMA format.
This may not only produce noise from the speaker damage, but also damage your hearing.Compression formats (Recommend: “Points to remember when making MP3/WMA files” on the previous page)∫Displayable characters≥Displayable length of file name/folder name: within 128 characters
≥Name files and folders in accordance with the standard of each file system. Refer to the instructions of writ-
ing software for details.

MaintenanceYour product is designed and manufactured to en-
sure a minimum of maintenance. Use a dry, a soft
cloth for routine exterior cleaning. Never use ben-
zine, thinner or other solvents.Product ServicingIf the suggestions in the charts do not solve the
problem, we recommend that you take it to your
nearest authorized Panasonic Servicenter. The
product should be serviced only by a qualified tech-
nician.
Replacing the FuseUse fuses of the same specified rating (15 A).
Using different substitutes or fuses with higher rat-
ings, or connecting the unit directly without a fuse,
could cause fire or damage to the unit. 
If the replacement fuse fails, contact your nearest
Panasonic Servicenter for service.
If you use commercial CDs, they must have
either of these labels below. ≥You may have trouble playing back some 
CD-R/RW discs recorded on CD recorders 
(CD-R/RW drives), either due to their recording
characteristics or dirt, fingerprints, scratches, etc.
on the disc surface.
≥CD-R/RW discs are less resistant to high temper-
atures and high humidity than ordinary music
CDs. Leaving them inside a car for extended peri-
ods may damage them and make playback im-
possible.
≥The unit may not successfully play back a 
CD-R/RW that was made by the combination of

The first step in installation is to identify all the car
wires you’ll use when hooking up your sound sys-
tem.
As you identify each wire, we suggest that you label
it using masking tape and a permanent marker. This
will help avoid confusion when making connections
later.
Note:
≥Do not connect the power connector to the stereo
unit until you have made all connections. If there
are no plastic caps on the stereo hooking wires,
insulate all exposed leads with electrical tape until
you are ready to use them. Identify the leads in
the following order.
Power Lead
If your car has a radio or is pre-wired for one: 
Cut the connector wires one at a time from the plug
(leaving the leads as long as possible) so that you
can work with individual leads.❐Identify All LeadsTurn the ignition on to the accessory position, and
ground one lead of the test bulb to the chassis. 
Touch the other lead of the test bulb to each of the
exposed wires from the cut radio connector plug.
Touch one wire at a time until you find the outlet
that causes the test bulb to light.
Now turn the ignition off and then on. If the bulb
also turns off and on, that outlet is the car power
lead.
If your car is not wired for an audio unit: 
Go to the fuse block and find the fuse port for radio
(RADIO), accessory (ACC), or ignition (IGN).
Battery Lead
If your stereo unit has a yellow lead, you will need
to locate the car’s battery lead. Otherwise you may
ignore this procedure. (The yellow battery lead pro-
vides continuous power to maintain a clock, memo-
ry storage, or other function.)
If your car has a radio or is pre-wired for one: 
With the ignition and headlights off, identify the car
battery lead by grounding one lead of the test bulb
to the chassis and checking the remaining exposed
wires from the cut radio connector plug.
If your car is not wired for an audio unit: 
Go to the fuse block and find the fuse port for the
battery, usually marked BAT.
Speakers
Identify the car speaker leads. There are two leads
for each speaker which are usually color coded.
A handy way to identify the speaker leads and the
speaker they are connected with is to test the leads
using a 1.5 V AA battery as follows.
Hold one lead against one pole of the battery and
stroke the other lead across the other pole. You will
hear a scraping sound in one of the speakers if you
are holding a speaker lead.
If not, keep testing different lead combinations until
you have located all the speaker leads. When you
label them, include the speaker location for each.
Antenna Motor
If your car is equipped with an automatic power an-
tenna, identify the car motor antenna lead by con-
necting one bulb tester lead to the car battery lead
and touching the remaining exposed wires from the
cut radio connector plug one at a time. You will
hear the antenna motor activate when you touch the
correct wire.
Antenna
The antenna lead is a thick, black wire with a metal
plug at the end.❐Connect All LeadsNow that you have identified all the wires in the car,
you are ready to begin connecting them to the
stereo unit wires. The wiring diagram (page 52)
shows the proper connections and color coding of
the leads.
We strongly recommend that you test the unit be-
fore making a final installation.
You can set the unit on the floor and make tempo-
rary connections to test the unit. Use electrical tape
to cover all exposed wires.Important:
≥Connect the red power lead last, after you have
made and insulated all other connections.
Ground
Connect the black ground lead of the power connec-
tor to the metal car chassis.
